Presentation Transcript


1. Speckle Reduction in Ultrasound Image Prepared by: Osama O. AbuSalah & Almoutaz Alhumaid Supervised by: Dr. Ali Saad

2. Objective provide the radiologist with better view of the Ultrasound image through reducing the noise without destroying important features .

3. Outline Introduction. Ultrasound equipment. Some Definitions. Programs method. Results. comparison Between different filters. conclusion & future work.

4. Introduction ultrasound machine participates strongly in the assistance of medical diagnosis and treatment. Ultrasound imaging is gaining more and more importance in medical practice nowadays. So its very important to gain the best results possible.

5. Ultrasound Equipment

6. definitions Speckle: A form of multiplicative noise corrupts medical Ultrasounds imaging making visual observation difficult. Filter: speckle noise removal by means of digital image processors to extract useful information about the scene being imaged.

7. Program method We used a Read & Write program that works on TIF images only. Read program converts image gray scale pixels into digital values. The filter deals with numeric values Write program converts back digital value into gray scale.

8. Spatial Filter method The method works by using a window as a sub image to estimate statistical measures. The sub image consist of neighborhood pixels which is called window (3x3, 5x5, 7x7,……).
